Abstract

This study was done to evaluate the effect of NaCl and Ca(OH)2 for preparing moringa (Moringa oleifera) seed extract used for turbidity removal from swine wastewater. The treatments were seed extract alone, only NaCl or Ca(OH)2 .and the seed extract prepared with NaCl or Ca(OH)2. Regression equations relating turbidity to the application rate were calculated. The data showed that the addition of moringa seed extract prepared in distilled water or NaCl solution, did not provide for turbidity removal from the wastewater. Practically, there was no difference in the turbidity removal between moringa seed extract and the extract prepared in Ca(OH)2 solution. The maximum turbidity reduction was obtained using 32 mL, (= 0.64 g L-1 ) of Ca(OH)2 solution or seed extract solution prepared in Ca(OH)2 (0.64 g L-1 of lime + 0,64 g L-1 of moringa seeds), with respective removal of 97.4 and 97.5% of the initial turbidity.
